Pride and Prejudice and Zombies adds martial arts and zombie attacks to Jane Austen's original novel. While keeping the core plot and characters intact, it transforms the story into an action thriller. Some critics see it as a commercial tactic, while others view it as a delightful reimagining. All of the characters are now skilled in martial arts and defend themselves from zombies. Social themes around class, wealth, marriage, and women's equality remain relevant in the revised story.
